A. Pump relay is energized providing power to the
hydraulic motor.
B. Energize the CUT Solenoid.
(Knife and Clamp are sent down).
C. De-energize the CUT Solenoid.
(Knife and Clamp are sent up).
The hydraulic motor is first run with the CUT solenoid
de-energized so that both the clamp and knife will be
in the extreme up position. When the electronics sense
that both the clamp and knife are up and the knife latch
is pulled in, the CUT solenoid will be energized.
When the CUT solenoid is energized, oil will flow freely
to the knife down (KD) cylinder port and through the
pressure reducing valve (Valve 16) to the clamp down
cylinder port (CD). Since oil is restricted by the knife
sequence valve (Valve 15) and blocked by a check
valve (Valve 14), the knife will stay up, and the clamp
will start down. When the clamp stops downward
motion, the system pressure will rise. Pressure in the
clamp down line will level off to the setting of the
pressure reducing valve (Valve 16). The system
pressure will continue to rise until the knife sequence
pressure valve (Valve 15) opens allowing the knife to
come down. The knife will continue down until the
cylinder reaches the extreme of its travel. System
pressure will increase until the main system relief valve
trips (Valve 9). At this time, the electronics will sense
that the knife is down, and de-energize the CUT
solenoid.
With the CUT solenoid de-energized, oil flow is directed
to the knife up cylinder port (KU) and the clamp up
cylinder port (CU). Since the clamp down port (CD) is
blocked by a check valve (Valve 14) and the clamp up
sequence valve (Valve 13), the clamp will stay down
while the knife goes up. When the knife reaches the
up extreme, system pressure builds until the clamp up
sequence valve (Valve 13) opens and allows the clamp
to go up. System pressure will increase until the main
system relief valve trips (Valve 9). At this time, the
electronics will sense that the knife and clamp are up,
and de-energize the pump relay (M).
